Hydraulic Monoblock Valve FM55/4 1/2 4P DDDS
Product description:
The FM55/4 1/2 4P DDDS is a four-section, high-flow hydraulic monoblock directional control valve featuring three DE (double effect) – double-acting – and one SE (single effect) – single-acting – working circuits. Each control lever is equipped with a spring return mechanism, ensuring automatic and safe return to the neutral position when released.
This valve from the FM55 series handles a 50 l/min nominal and up to 70 l/min maximum flow rate, while tolerating up to 300 bar maximum operating pressure. The built-in pressure relief valve is adjustable between 100–250 bar, factory-set at 140 bar. The 1/2" BSP ports provide high flow capacity with minimal pressure loss across all sections.
Technical specifications:
- Nominal flow rate: 50 l/min
- Maximum flow rate: 70 l/min
- Nominal pressure: 280 bar
- Maximum operating pressure: 300 bar
- Max. tank line pressure: 80 bar
- Relief valve setting range: 100–250 bar (factory: 140 bar)
- Number of sections: 4
- Spool type: DDDS – three double-acting and one single-acting circuit
- Inlet/outlet ports: 1/2" BSP
Applications:
- Combined hydraulic systems (3× DE + 1× SE)
- Control of lifting, tipping and auxiliary cylinders
- Agricultural and industrial hydraulic systems
- High-flow, multi-circuit hydraulic machinery
The FM55/4 1/2 4P DDDS valve is an ideal solution for applications requiring powerful, precise and reliable control of mixed-function hydraulic circuits within a single compact monoblock valve.
